Entourage, the movie?
Mark Wahlberg has stated in an interview that he believes that Entourage, the HBO show in which he serves as executive producer, has two more years left in its television life before making the jump to the theatrical screen. The show has just been renewed for a sixth season.
It's not a bad idea, although the concept of a Hollywood insider movie has been done in Hollywood movies before, most notably with Robert Altman's The Player. However, it's been 17 years since that movie was released, so its ripe for recycling (It's surprising it hasn't been redone yet).
HBO has seen tremendous success with one of its franchises moving to the big screen, Sex and the City (which has a sequel on the way). On the other hand, The Sopranos hasn't made it to the big screen yet for some reason. Perhaps David Chase didn't want to ruin a perfect ending to the series.
